S-93339A248 M4 x 10 mm Set Screws

Key Features & Benefits at a Glance

• Maximum holding power with Class 6g thread fit ensuring secure, vibration-resistant fastening in demanding applications
• Superior durability from Rockwell C39 hardness alloy steel construction resisting wear and deformation under heavy loads
• Precise positioning with 2.5mm ball tip design providing positive seating and reduced component damage during installation
• Space-saving installation through headless hex drive design allowing flush mounting in confined assemblies
• Quick assembly with 2mm hex drive enabling efficient installation using standard metric tools
• Reliable performance in industrial environments with coarse M4x0.7mm thread profile maintaining grip under vibration
• Environmental compliance meeting RoHS 3 standards for use in regulated industries and international supply chains

Professional Applications & Engineering Value

This M4 set screw delivers critical engineering solutions for precision assembly challenges. The alloy steel construction with Rockwell C39 hardness provides exceptional resistance to shear forces and repetitive stress, making it ideal for permanent positioning applications in machinery, automotive components, and electrical enclosures. The ball tip design distributes clamping force evenly while minimizing surface marring, particularly valuable when securing gears, pulleys, and collars on shafts. The hex headless configuration enables flush mounting in space-constrained assemblies where protruding fastener heads would interfere with adjacent components. With Class 6g thread tolerance and coarse thread pitch, this metric set screw maintains reliable grip even in high-vibration environments, reducing maintenance requirements and preventing costly production downtime.

Specification Summary & Compliance

This precision fastener features M4x0.7mm coarse thread with Class 6g tolerance per metric standards, ensuring consistent threading compatibility. The 10mm length provides optimal engagement depth for most industrial applications. Manufacturing complies with RoHS 3 (2015/863/EU) regulations with exemption 6(a) for lead as an alloying element in steel, making it suitable for international markets with strict environmental requirements. The right-hand thread direction and 2mm hex drive conform to global industrial standards for tool compatibility and installation efficiency.
